Thinnest AI - Pros & Cons
Pros
- ✓Very transparent pricing compared with many voice AI vendors, including a real free trial and published enterprise discount floor
- ✓Strong multilingual coverage, especially for Indian languages that many global voice vendors treat as secondary
- ✓BYOK model means no forced markup on LLM, STT, TTS, or telephony vendors
- ✓Supports both no-code teams and developers through flow editor, APIs, SDKs, and SIP integrations
- ✓Explicit compliance and billing posture makes it easier for India-based teams to evaluate operational fit
Cons
- ✗Total cost is not just ₹1.5/min because LLM, STT, TTS, and carrier charges still pass through separately
- ✗Best value is clearest for teams operating in or serving India; global buyers may compare more directly with Vapi or Retell
- ✗Builder-oriented platform, so non-technical teams may still need help configuring prompts, routing, and provider choices
- ✗Published self-positioning such as cheapest-in-India claims should still be validated against your exact shortlist before committing
- ✗Voice quality, latency, and accuracy will vary based on the providers you bring to the stack
LiveKit - Pros & Cons
Pros
- ✓OpenAI's Realtime API for Voice runs on LiveKit — production-validated at the highest scale
- ✓Turn detection, interruption handling, and SIP/PSTN bridges are battle-tested out of the box
- ✓Apache 2.0 self-host path is real — same SDKs, your own infra, no vendor lock-in
Cons
- ✗Developer-only with no no-code agent builder — slower first hour than Vapi or Retell
- ✗You own the LLM + STT + TTS + tools integration surface, so testing burden is higher
- ✗Managed Cloud costs can climb on long-duration calls without session-lifetime tuning
